1911. snat no. ecarte( 'may concern; Be it known-that I, ERIK AUGUST Fons- BERG, 'a subject of the King ofSweden, .residing at Stockholm, Sweden, have invented aniew and usetul Improvement in Centrifugail Liquid-Separators, of which the foland exact descrip- -the accompanytion,referen'ce beii1g had to this :ing drawings, which "form apart o specification.'A

My invention 'relates particularlyfto ay certain new-form and construct-ion of di.- vision plates which are used in liners Jfor vThese plates, or,'as they are called, disks, are generally conical and generally have straight fmantles or sides so that-.the spaces'bet'ween disks or plates are the same romf'the inner to .the outer ends thereof. 1 r I There y .has been :patented .by Fredrki 'L3' ungstronnl ot viSweden (United StatesI Letters Iate'nthlm ,892,949.9d'ated July 14th 1908) a construction in which the 'disks or vplates are str-.formed that the; spaces between a diskor', .plateand its. adjacent disks or gradually narrowed from the in snij saidspaces outward. In the construction 'shown and described in this patent thonet is agjspace between ds ofthe plains) or. .disks-and the l bowl, thus forming .plates through whichA to 'its outlet and in y matter may be depdsitedL 4My invention, so far as the form or construction of the plates, which produces a condition in which the width of the spaces` between any given plate and its-adjacent' plates are gradually narrowed from the in;- ner ends ot said. spaces outward, is conrei-ned, is that shown vin the Ljungstrom. patent. On the other hand, instead of, as vin the Ljungstroin patent, thedisks termi"- nating an Aappreciable distance from the inner periphery of the bowl so as to forma skimrnilkiiow and foreign matter 'passagebetween the ends of the plates and thewin; ner periphery ofthe bowl, I adopt a novel construction which, in conjunction with .the

vthe .outer en inner peri hery ci .th

a passage eyronjdzthe In my inven ion the disks or plates are extended practically.v to the inner periphery bowl',t he're being only such clearance the disks and the 55 will enable between.. the Outer ed '.inner periphery ofv the bowl as ot the ges of .the inlet tube; c the slot or openings wl distribute the full milk between for plates.

V'ends of adjacent disks is greater than' the .'tially to-'the inner perip the ready rem0val.and replacemento the I disks or plates and their proper-operation. Ata; short distance inward from the bowl, I provide the' disks or plates with open- Lings, apertures, ororices for the passage zof the skiinniilk tothe'exit point thereof from the bowl. There isstilldcftbetween these orifices or holes.'and the inner :periph- -ery of the bowla slightl space in ,which the foreign matter eaneollect, between the disks 6&5 or plates and maya-ttach itself-'to the sui:- face of the. disks Olliplates, While, in my invention, I take advantage of. the results: produced by the invention forming' the sub- )ect-matterizof the said patent ot' Fredrik'm Ljungstrom, No. 892,999, onthe ,other hand, obtain certain additional Ladvaniagcs, among which maybe inentionedihe. tactihatv theskimlnilk, ,in itsl upward, travel' to the skiininilk outlet, is still conlinedibetw een 01:5

the 4disks and is therefore subjected ,to fur.- -ther s k'mming under a positivecondition for the 4production' of additional cream. g-Furt-her, any foreign matter may be 'cbllected and removed more readily as it will at? tachv to the surface of the disksbeyondthe skimmilk orifices of the bowl and can be ,removed simultaneously, wit-h'the regular cleaning of the disks.

, ,I., .will now describe the emhodmentaoi mv invention as illustrated in the accom-- panying drawing, which shows asectionpi a bowl haviiig'therei'n 'iniprov liner. Inthis drawing a," is therotating bowl b uc i the disks d are the plates which are curved, as that the space between'the inner shown, so

space between the same disks at the outer end, and moreover, this space gradually-,decreases Jfrom the innerto the outenend.; '.As .may be seen, these disks extend. substana heryi o t the, boing-10o there being, as stated'before, merelycl ancesuificient for operationfy e is the skimmilk discharge tube;ami{]4 are apertures, openings or holes throughsthe-@ disks or plates for the passage ofthe skim-1 A-105 milk to the discharge tube e. v The operation may be readily understood.. Full milk passes in through thefcentral -ieed tube I) and is projected -by the slotor-slotted 'wing c? simultaneously between,

' full Y. milk or plates. Thev crea-m" passes up near the center wall. The skilnmilk passes upward to the orices f' and escapes through the skimmiik delivery tube or `discharge tube e. Any foreign matter will be found beyond these oritices or holes f andmainly attached to ,the surface of the disks from which-it may readily be removed when the disks are cleaned. p

Having now fully described my invention, .what I claim and desire to protectl by Letters Patent is 1. In a centrifugal liquid separator, the a bowl having anl ,outlet for the skim milk, of a lil-ier consisting of a series of superimposed separating plates extending from near the axis ofthe bowl substantially to the inner periphery vof the bowl and forming passages between adjacent plates, each plate being so formed-that the width of the spaces between it and its adjacent plate are less at the outer than at the inner end of said spaces, there being apertures through said plates for conveying the `skim milk t' the skim milk outlet.

2.In a centrifugal liquid separator, the combination with a bowl having an outlet for the skim milk, of a liner consisting of .a 'series of superimposed'separating plates extending from near the axis of the bowl substantially to the inner periphery of the bowl and forming passages between adjaeach plate being so formed that adjacentplate are less at the outer than at the inner end of said spaces, there being,

apertures through said plates for conveying tothe skim milk outlet, and means independent of the disks to feed the other -liquid to be separated simultaneously the plates.
